Subject: [PATCH] chore(ci): disable branch coverage for now

We've pinned the Rust nightly to a specific version, because it caused
some problems when generating the coverage. Seems like the issue hasn't
been fixed yet, while a newer nightly version introduced some formatter
changes, so it's difficult to stay on the pinned version any longer.

This disables the nightly-only branch coverage calculation and upgrades
the Rust nightly version in the CI.

Relevant issues:
* llvm/llvm-project#119558
* taiki-e/cargo-llvm-cov#8
